Copper sealing gasket Kubota 6C090-58961. The part is used for processing fluid drain plugs in the Kubota D902 engine used in the Shindaiwa DGW400 Diesel Welder.
The gaskets for oil, water and fuel drain plugs are the same size. The uniform shape of the copper gaskets is convenient as there is no need for an extensive size range. This Kubota engine spare part is thick, so it can be reused if you do not have a new gasket available during service.
